Galeocerdo eaglesomei, Burleson Co. Lutetian, Eocene May, 2023 Finally found a beautiful Galeocerdo eaglesomei. Carcharhiniformes are not well represented in my mostly Mesozoic collection so I was really happy to find this guy. It came out in two pieces, but b72 did the trick for a quick fix.-

Striatolamia macrota, Burleson Co. Lutetian, Eocene May, 2023 Took one last trip to the bridge on the way to help my brother move out of his dorm. It was raining hard the whole way there, but the rain stopped as I got to the spot. Super muddy, but worthwhile to find some shark teeth freshly eroding out for this quick visit. This is my best example of Striatolamia macrota.-

Echinoid Eupatagus antillarium commonly called the Florida sea biscuit.... I have found many of these over the years but this one is the first one that I have ever found that may show signs of predation? What does everyone think? Thanks for you input!

Hi guys I recently purchased a few croc teeth from popes creek which ranges from eocene to miocene I believe any idea on the species here @pachy-pleuro-whatnot-odon @Praefectus 1. 2. 3.

Found in NJ Miocene/Eocene stream. It has weird grooves on the outside patina, and on the inside has corresponding grooves. It comes to a point as you can somewhat make out in the third image. Any ideas what it could be?

Hello everyone. I am after the ID of these solitary corals. Location: Eastern Bulgaria, Rhodope Mts, south of Kardzhali Age: Oligocene, did not manage to pinpoint the exact location on the geological map, due to poor quality map. As per a local expert, the horn-shaped coral is a Placosmiliopsis bilobatus and the age is Oligocene. The species is supposed to have polymorphy; some are roundish, while others form slightly the number 8. I found a topic on a Spanish forum but I fail to understand the key elements determining the species. Through the help of Google translate, I understood that I have to create cross sections (vertically? horizontally? I made both) but I do not understand what I should observe. (Spanish text in the end of this post) Additionally, as per minedat, the P. bilobatus is supposed to have gone extinct up to Priabonian. This is the reason I started searching since one fact is against the other. The horn-shaped coral is approx an inch in diameter and 1.25" height. The discoid coral has a diameter of 1.75" and 0.25" thick. Both were cleaned with toothbrush and KOH. @fifbrindacier said that @oyo and @HansTheLoser might be able to help on this topic. I would appreciate your opinion. Thank you! "Placosmiliopsis: columnella laminar profunda / Pattalophyllia: columnilla trabecular. Solo hay que cortarle a un cucurucho su rabito y pulirlo un poco (con una muela de afilar cuesta poco), para ver si tiene una columnilla en lámina continua o una columnilla también lineal pero por una amalgama de trabéculas.... como en las últimas fotos de los links que ha puesto Elotro... ....para mi que es Pattalophyllia." This what it is supposed to be Placosmiliopsis bilobatus. There are some noumoulites or other foraminifera on top of it. Horizontal section Vertical section The other type of coral, found at the same locality.

Thought this pic looked nice and almost like an old school oil painting. I like that the pillar of the railroad track appears as if it were a continuation of the natural bluff farther back. -

I found a very odd fossil at whiskey bridge over the weekend and was wondering if anybody had any knowledge on what it could be, picture attached isn't the very best but I'm too afraid the remove it from the bag protecting it right now due to fragility, planning on properly preparing it once i get some paraloid in. BUT the fossil is about 4-5 inches long and 2-3 inches across, it is very fragile towards the end of it but the stem seems to be more sturdy. sorry again for poor picture and lack of scale, just don't want to risk further damage to the fossil yet. My only current guesses are a large piece of coral or some sort of vegetation. either way i know finds of this size aren't very common from whiskey bridge. thank you for any help with identifying.

From the album: Sharks
An early Lamnid (family that includes the modern great white and mako sharks) from Central Kazakhstan. Some consider this genus to be ancestral to Carcharodon or both Carcharodon and Isurus. The latter is a tempting hypothesis since molecular clock studies place the last common ancestor of the great white and makos in this time. -
This fish has been known for decades among collectors as "Argentina sphyraena" and has only recently been described as Surlykus longigracilis. It is the most abundant fish from the Eocene Fur Formation of Denmark. Etymology: Genus named in honor of professor emeritus Finn Surlyk, The species name is derived from the Latin words ‘longus’ (long) and ‘gracilis’ (slender) referring to the body shape.
